Is a website, is beautiful, is easy to use, has an API. You've hit on the first three, so when the API becomes public, I am so using this.
Are you hosting this yourself? Do you expect $9/year members to adequate cover the costs? I'd totally be willing to pay more if it means I don't have to suffer through another shutdown.
A few people have mentioned wanting to donate more. I could make a few more options for the donation amount. I figured I was on the high end at $9/yr. People don't like paying for software anymore.
